At the time of voting, there were 526 instances of shop=bookmaker and 496 instances of shop=betting. At the moment, there are 1054 instances of shop=bookmaker and 519 instances of shop=betting. This suggests that newly added bookmakers typically follow the approved tagging scheme, while many old bookmakers remain in place that follow the shop=betting scheme.

Having only one form makes life easier for both mappers and data consumers.

I realize that automatic edits are often undesirable. When badly executed, automatic edits can easily introduce additional mistakes, especially when executed by mappers without local knowledge. Automatic edits can also have undesired side-effects. Moreover, automatic edits might offend mappers who do not agree with the edit.

In particular, I recognize that it is important that:

automatic edits have wide community support;

automatic edits do not introduce mistakes or otherwise destroy the work of local mappers.

I believe that in this case, both of these requirements are satisfied.

I will discuss this edit at the talk-gb mailing list (link). Although not formally required, in order to guarantee community support, I will invite list members to vote on this automatic edit. I will not proceed without at least 8 votes with 2/3 approval.

Technical implementation

I will used JOSM combined with Overpass.

I will download the data from overpass, manually select the UK only, and run the following filter:

shop=betting and (name=Betfred or name=Coral or name=Ladbrokes or name="Paddy Power" or name="William Hill")

Subsequentially, I will change the tag shop=betting to shop=bookmaker, and upload the data.

I approve this proposal. This proposal takes care to limit itself to objects that we can be confident about. Proposal was nicely discussed on Talk-GB list first. --Danstowell (talk) 20:54, 29 October 2014 (UTC)

I approve this proposal. SK53. You may also want to include or perform same edit later on some of these minor values! SK53 (talk) 11:25, 30 October 2014 (UTC)

I approve this proposal. (It might also be productive to look at any remaining UK shop=betting values manually after this mechanical edit has been completed, to see what's been missed.) -- Rjw62 (talk) 11:32, 30 October 2014 (UTC)
